On July 6 I installed the updates v16.63 (2207500) and in New Outlook the signatures from all four of the email accounts I have, have all disappeared. They are not visible in SIgnatures, and the '+' button in Edit Signatures does nothing – I can't recreate the signatures. I've upgraded to v16.63 (22070801) but no change.
I switched back to Legacy Outlook nd the signatures were all there, and I could edit and add signatures. Switching back to New Outlook, my signatures had reappeared, but once I restarted my MacBook, in New Outlook the signatures are not present and I cannot add any.

Any help gracefully received. I've tried the customer Customer Support button but the chat responses are painfully slow - conversation has been going on since July 7th with diagnostic questions taking 18-48 hours to appear.

Sean,
When I started to experience a problem with my signature templates, I created a Word doc with the templates that I keep on my desktop. Meanwhile, they seem to have magically reappeared in Outlook. Hopefully, this is a permanent arrangement.
